The law does not permit terms to be changed by one party to a rental agreement, during the life of the agreement, without advance notice. For example, if a landlord wishes to legally increase the rent then he or she must provide notice to the tenant. The notice is effectively a way of terminating the current agreement and offering to enter a new agreement. The tenant has the right to stay in the rental property at the current rent for the remainder of the current lease and then can decide to agree to the increase or to leave the property. Other terms may be legally varied in a similar manner. This situation only applies when the landlord and tenant have not expressly agreed to a different form of notice. For more information on W.Va. Code ยง37-6-5 and Notice see Section 3.
